is it possible to keep the texture attached to my project?
To make sure that all the images you use are part of your blend file you can go into the File menu &gt; External Data &gt; Automatically Pack Into .Blend. If you don't want to make it automatic but just want to pack the current images, choose Pack All Into .Blend.

If you want to do it for just one or several images, you can go in the UV Editor or Image Editor, select the image you want, and Image menu &gt; Pack.
